L2 Networks

Architecture

L2 Networks, within cryptocurrency and derivatives, represent off-chain scaling solutions built atop a base layer blockchain, typically Ethereum. These systems aim to enhance transaction throughput and reduce associated costs by processing transactions outside the main chain, subsequently settling them periodically on Layer 1. The architectural design often involves state channels, rollups (optimistic or zero-knowledge), or validium, each employing distinct cryptographic techniques to ensure data integrity and security. Effective implementation necessitates careful consideration of data availability, fraud proofs, and the trade-offs between scalability, security, and decentralization.
